[0002] This application relates to the field of display technology, specifically to display panels and display devices. Background Technology

[0003] Antennas are important components of smart terminal devices such as smartphones. With the active development of mobile communication technology, 5G communication technology has become increasingly popular. However, due to the popularization of 5G communication technology, the number of mobile phone antennas has increased significantly, while mobile phone bezels are becoming narrower, mobile phone thickness is decreasing, and the interior is being compressed. Consequently, there is a severe shortage of space to place antennas inside the mobile phone, leading to lower communication efficiency and increasing challenges for technicians.

[0004] The present application provides a display panel and a display device, which can solve the problem of low communication efficiency in smart terminal devices such as mobile phones.

[0005] In a first aspect, an embodiment of the present application provides a display panel, wherein the display panel includes a first display area and a second display area, the second display area includes a first area and a second area disposed adjacently, a first antenna disposed within the first area and a second antenna disposed within the second area, and the display panel further includes a touch control electrode disposed within the first display area and the second area.

[0006] In another aspect, an embodiment of the present application provides a display device comprising a display panel of any one of the embodiments described above.

[0007] In a display panel and display device according to an embodiment of the present application, a first antenna is placed in a first area of ​​a second display area, a second antenna is placed in a second area of ​​the second display area, and a touch control electrode is simultaneously placed in the second area. That is, by integrating the antenna in the second display area of ​​the display panel, the second display area can implement not only a display function but also an antenna function. Since there is no need to place a separate antenna area for the first antenna and the second antenna, it is advantageous for the lightweighting of the display panel and the implementation of a high screen occupancy rate design. In this case, only the first antenna is placed in the first area to ensure the placement space for the first antenna and reduce the risk of touch misoperation in the first area. In the second area, the second antenna is placed and a touch control electrode is also placed. That is, the second area can implement not only a touch control function but also an antenna function. At the same time, the antenna integration design can be performed better by rationally utilizing the second area without affecting the touch control function of the second area, and the communication efficiency of the display panel can be improved.

Specific details for implementing the invention

[0009] Antennas are a critical component of smart terminal devices and enable their communication functions. When deploying antennas, a certain clearance area must be ensured to prevent other components from affecting their communication performance. 5G communication technology requires more antennas, which runs counter to the design demands for smart terminal devices, such as smartphones, to become increasingly lighter, thinner, smaller, and more aesthetically pleasing. Insufficient clearance for internal antennas makes mobile communication, particularly high-frequency communication, susceptible to interference, thereby impacting communication performance. Therefore, it is challenging to implement smaller mobile phones capable of accommodating more antennas to improve the communication efficiency of smart terminal devices like mobile phones.

[0010] Based on this, the embodiments of the present application provide a display panel and a display device, which can solve the technical problem of insufficient space for placing an antenna inside a smart terminal device.

[0011] Referring to FIGS. 1 through 7, a display panel (100) includes a first display area (PL) and a second display area (BE), and the second display area (BE) includes a first area (BE1) and a second area (BE2) that are arranged adjacently, and a first antenna (120) is arranged within the first area (BE1), and a second antenna (130) is arranged within the second area (BE2). The display panel (100) further includes touch control electrodes arranged within the first display area (PL) and the second area (BE2).

[0012] Specifically, depending on the different shapes of the display panel (100), the relative positions and respective shapes of the first display area (PL) and the second display area (BE) are not completely identical.

[0013] For example, the first display area (PL) may be rectangular, circular, or elliptical, and the second display area (BE) may be placed around the first display area (PL), or inside the first display area (PL), or may be selected as needed. When the second display area (BE) is placed around the first display area (PL), the second display area (BE) may be placed around the entire first display area (PL) or around a part of the first display area (PL). Optionally, when the first display area (PL) is rectangular, the second display area (BE) may be placed on one side or multiple sides of the first display area (PL).

[0014] Optionally, the first display area (PL) may be arranged as a flat or curved surface, and the second display area (BE) may also be arranged as a flat or curved surface, and the specific shapes of the first display area (PL) and the second display area (BE) may be selected according to actual demand.

[0015] In some embodiments, as illustrated in FIG. 1, both the first display area (PL) and the second display area (BE) may be curved, and when the corresponding display panel (100) is applied to a display device, the display device is a curved display device or a flexible display device. In other embodiments, as illustrated in FIG. 2, both the first display area (PL) and the second display area (BE) may be flat, and when the corresponding display panel (100) is applied to a display device, the display device is a flat display device. In some embodiments, as illustrated in FIG. 4, the first display area (PL) is flat and the second display area (BE) is curved, for example, formed by bending the edge of the first display area (PL), and by arranging them in this way, the object of the invention of the present application can still be realized.

[0016] Optionally, the first display area (PL) may or may not be foldable, and FIG. 3 shows an example in which the first display area (PL) of the display panel (100) can be foldable.

[0017] The display panel (100) may be an Organic Light Emitting Diode (OLED) display panel (100) or a Liquid Crystal Display (LCD) panel (100).

[0018] The first antenna (120) may be a graphic structure and the second antenna (130) may also be a graphic structure, and the graphics of the first antenna (120) and the second antenna (130) may be set according to actual demand, and the present application is not limited thereto.

[0019] A touch control electrode (110a) is disposed within the second region (BE2), that is, the second region (BE2) is disposed to have a touch control function. The touch control form of the second region (BE2) may be a self-capacitance form or a mutual capacitance form, and the different touch control forms correspond to different structural forms of the touch control electrode (110a).

[0020] Referring to FIG. 6, in some embodiments, the touch control form of the second region (BE2) is mutually capacitive, where the touch control electrodes (110a) may be electrode blocks arranged in a plurality of identical layers and distributed in an array, and the touch control electrodes (110a) in the row of the same matrix or the column of the same matrix are electrically connected to each other.

[0021] In some other embodiments, the touch control form of the second region (BE2) is a self-capacitance form, wherein the touch control electrode (110a) includes a touch driving electrode and a touch sensing electrode arranged in an insulated manner, one of the touch driving electrode and the touch sensing electrode extends in a row direction and the other extends in a column direction, and capacitance may occur at the location where the two intersect.

[0022] Referring to FIG. 6, a second antenna (130) and a touch control electrode (110a) are simultaneously placed in the second area (BE2) of the second display area (BE), that is, the second area (BE2) has an antenna function and also a touch control function. Only a first antenna (120) is placed in the first area (BE1) of the second display area (BE), so that the first area (BE1) has only an antenna function and does not have a touch control function, thereby reducing the risk of affecting the antenna function of the first area (BE1) due to touch misoperation on the first area (BE1) and ensuring that the first area (BE1) has sufficient space for the placement of the first antenna (120).

[0023] It should be explained that when the second region (BE2) samples the antenna signal and the touch control signal, it may sample them simultaneously or alternately. In some embodiments, to prevent mutual interference between the two types of signals, signal sampling for the antenna signal and the touch control signal of the second region (BE2) may be performed using a time division multiplexing method.

[0024] Specifically, the antenna signal and the touch control signal can be sampled according to the same time period, and if the sampling pulse width is sufficiently narrow, there is a constant time interval between two sampled values ​​of the same type of signal. If the sampling time of a different type of signal happens to be within the said time interval, the sampled values ​​of the two types of signals do not overlap in time. Optionally, the usage period of the antenna signal and the touch control signal can be set to any value between 1 μs and 10 ms, and can be selected according to specific needs. By using this control method to sample the antenna signal and the touch control signal, the second antenna (130) and the touch control electrode (110a) share the same space so that the second region (BE2) combines the antenna function and the touch control function, and at the same time, since both perform signal sampling alternately, they do not cause signal interference with each other.

[0025] A first antenna (120) is placed in the first area (BE1) of the second display area (BE), and the position of the first area (BE1) in the display panel (100) is set according to the actual situation to achieve a high screen occupancy rate of the display panel (100). In the first area (BE1), only the first antenna (120) is placed to have only the function of receiving or transmitting signals and not to have a touch control function. By placing it in this way, a sufficient clearance area is provided to the first antenna (120), thereby improving the communication efficiency of the first antenna (120) and reducing the risk of touch misoperation. In addition, since only the first antenna (120) is placed in the first region (BE1) and the touch control electrode (110a) is not placed, unlike the second antenna (130) and the touch control electrode (110a) which alternately perform sampling of the antenna signal and the touch control signal, the first antenna (120) can continuously perform the reception and transmission of information, that is, the first antenna (120) can continuously perform the function of an antenna.

[0026] Optionally, the first antenna (120) and the second antenna (130) may both be millimeter wave antennas, and the first antenna (120) may be the main antenna and the second antenna (130) may be an auxiliary antenna that amplifies the signal of the first antenna (120), and when the second antenna (130) is multiplexed to the touch control electrode (110a), the first antenna (120), i.e., the main antenna, may communicate independently.

[0027] In a display panel (100) according to an embodiment of the present application, a first antenna (120) is placed in a first area (BE1) of a second display area (BE), a second antenna (130) is placed in a second area (BE2) of the second display area (BE), and a touch control electrode (110a) is placed simultaneously in the second area (BE2). That is, by integrating the antennas in the second display area (BE) of the display panel (100), the second display area (BE) can implement not only a display function but also an antenna function, so there is no need to place the antenna area alone, which is advantageous for achieving a lightweight display panel (100) and a high screen occupancy rate. In this case, only the first antenna (120) is placed in the first area (BE1) to ensure the placement space for the first antenna (120), and the risk of a touch misoperation on the first area (BE1) affecting the function of the first antenna (120) may be reduced. In the second area (BE2), a second antenna (130) is disposed and a touch control electrode (110a) is also disposed. That is, since the second area (BE2) can implement an antenna function and a touch control function, the second area (BE2) can be utilized in a reasonable manner to better perform antenna integration placement without affecting the touch control function of the second area (BE2), thereby improving the communication efficiency of the display panel (100).

[0028] The number of first areas (BE1) and second areas (BE2) within the second display area (BE) can be selected according to demand, and may be one or multiple, and multiple first areas (BE1) or multiple second areas (BE2) are distributed intersectingly. The shape and size of multiple first areas (BE1) may be identical or different, and may be arranged according to actual demand.

[0029] In some embodiments, the second display area (BE) is arranged in a strip shape and extends along the edge of the first display area (PL).

[0030] Specifically, depending on the different edge shape of the first display area (PL), the second display area (BE) may be a strip shape of a different shape. For example, if the edge of the first display area (PL) is arc-shaped, the second display area (BE) is an arc-shaped strip, and if the edge of the second display area (PL) is straight, the second display area (BE) is a straight strip shape, that is, the second display area (BE) extends linearly.

[0031] Optionally, the second display area (BE) may be flat or curved.

[0032] If the second display area (BE) is placed at the edge of the first display area (PL), it is convenient to integrate the first antenna (120) and the second antenna (130) within the second display area (BE). Additionally, if the first antenna (120) and the second antenna (130) are placed using a strip-shaped second display area (BE), the second display area (BE) can have an antenna function while also having a display function, making it convenient to achieve a high screen occupancy rate of the display panel.

[0033] In some embodiments, in the extension direction (X) of the second display area (BE), the first area (BE1) is located at an intermediate position of the corresponding second display area (BE), and at least two second areas (BE2) are each placed on both sides of the first area (BE1).

[0034] For example, one first area (BE1) and two second areas (BE2) can be arranged, with the two second areas (BE2) located on each side of the first area (BE1) along the extension direction (X). Alternatively, two first areas (BE1) and three second areas (BE2) can be arranged so that the two first areas (BE1) and three second areas (BE2) are alternately distributed along the extension direction (X). Of course, more first areas (BE1) and second areas (BE2) can be arranged, and this can be selected according to specific placement needs.

[0035] By arranging them in this way, both ends of the second display area (BE) along the extension direction (X) become the second area (BE2), making it more convenient for the operator to perform touch operations on the second display area (BE).

[0036] In some optional embodiments, the extension length of the second display area (BE) is L1, and the length of the first area (BE1) along the extension direction (X) of the second display area (BE) is L2, and 30%≤L2 / L1≤50%.

[0037] Specifically, referring to FIG. 4, the second display area (BE) includes one first area (BE1) and two second areas (BE2) located at both ends of the first area (BE1) along the extension direction (X). Since the first area (BE1) has only an antenna function and no touch control function or touch-related element is placed therein, and the second area (BE2) has a touch control function, there is no need to perform touch operations on the first area (BE1). Therefore, if the first area (BE1) is placed in a position close to the middle of the second display area (BE), the risk of accidental touch operation on the first area (BE1) can be further reduced. At the same time, the second area (BE2) is placed at both ends along the extension direction (X) of the second display area (BE), and since the second area (BE2) has a touch control function, it is more convenient for an operator to perform touch operations on the second area (BE2).

[0038] For example, the first region (BE1) is located at the center of the second display region (BE) along the extension direction (X), and the extension lengths of the second region (BE2) at both ends along the extension direction (X) are the same.

[0039] L2 / L1 may be 30%, 35%, 40%, 45%, or 50%, etc., and, for example, the second display area (BE) can be divided into three parts by arranging the first area (BE1) and the second area (BE2) at both ends. By arranging in this way, it can be ensured that the second display area (BE) has sufficient space to accommodate the first area (BE1) of the first antenna (120), and the risk of an operator's touch error on the first area (BE1) is reduced, while the second area (BE2) has a touch control function, making it more convenient for the operator to perform touch operations on the second area (BE2) of the second display area (BE).

[0040] The first antenna (120) may be placed on the same layer as the second antenna (130) and the touch control electrode (110a), or on a different layer, and may be selected according to specific needs. For example, the first antenna (120) and the second antenna (130) may be placed on the same layer, and the first antenna may be placed on a different layer from the touch control electrode (110a).

[0041] In some embodiments, the second antenna (130) and the touch control electrode (110a) are placed on the same layer.

[0042] Specifically, referring to FIGS. 6 and 7, the display panel (100) includes a substrate (140) and a touch control layer (110) disposed on one side of the substrate (140), the substrate (140) may include a light-emitting structure, a touch control electrode (110a) is disposed on the touch control layer (110), and a second antenna (130) is also disposed on the touch control layer (110), and referring to FIGS. 9 and 10, an embodiment is shown in which the touch control electrode (110a) and the second antenna (130) are disposed on the same layer.

[0043] Depending on the different touch control type of the second region (BE2), the display panel (100) may include one or more layers of touch control layers (110), and the touch control electrode (110a) in the second region (BE2) may be placed in two or more layers of touch control layers (110), and the second antenna (130) may be placed in a film layer of any one of the touch control layers (110) and spaced apart from the touch control electrode (110a) or lead wire of the film layer to reduce signal interference between them.

[0044] By placing the second antenna (130) and the touch control electrode (110a) on the same layer, the second antenna (130) can be placed using the gap between the corresponding touch control electrodes (110a) in the touch control layer (110), thereby enabling the implementation of the touch control function of the second region (BE2) or providing an electrical signal for the implementation of the touch control function, and also providing an antenna function, while simultaneously eliminating the need to place a single film layer on the second antenna (130), thereby effectively reducing the thickness of the display panel (100).

[0045] For example, when the touch control type of the second region (BE2) is a self-capacitive type, the touch control layer (110) includes a touch driving electrode layer and a touch sensing electrode layer that are disposed insulated, and the second antenna (130) may be disposed in the touch driving electrode layer or in the touch sensing electrode layer.

[0046] Optionally, the touch control form of the second region (BE2) may be mutual capacitance form, wherein the touch control layer (110) may include a touch control electrode layer and a bridge layer, wherein the touch control electrode (110a) is disposed in the touch control electrode layer, and the second antenna (130) may be disposed in the touch control electrode layer.

[0047] Through the above-described arrangement, the touch control function and antenna function of the second area (BE2) can be implemented, while the thickness of the display panel (100) can be reduced.

[0048] In an embodiment where the second antenna (130) and the touch control electrode (110a) are placed on the same layer, the first antenna (120) may be placed on the same layer as the second antenna (130) and the touch control electrode (110a) or on a different layer, so that all can implement the antenna function of the first region (BE1).

[0049] In some embodiments, the first antenna (120) and the touch control electrode (110a) are placed on the same layer. In other words, the first antenna (120), the second antenna (130), and the touch control electrode (110a) are all placed on the touch control layer (110), thereby further reducing the thickness of the display panel (100).

[0050] Specifically, when a touch control electrode (110a) is placed in a first display area (PL) and also in a second area (BE2), and a first antenna (120) and a second antenna (130) are placed in a second display area (BE), the film layer of the second display area (BE) and the corresponding film layer of the first display area (PL) can be formed together. By arranging them in this way, the thickness of the display panel (100) can be further reduced.

[0051] In some other embodiments, the display panel (100) includes a touch control layer (110) and an antenna layer that are stacked and arranged, a touch control electrode (110a) is placed in the touch control layer, and a second antenna (130) is placed in the antenna layer.

[0052] In other words, the touch control electrode (110a) and the second antenna (130) are placed on different layers, and may be located on adjacent film layers or on one or more film layers at a distance.

[0053] By placing the touch control electrode (110a) and the second antenna (130) on different film layers, the difficulty of processing the display panel (100) can be reduced and the risk of a short circuit between the second antenna (130) and the touch control electrode (110a) can be reduced.

[0054] In some embodiments, as shown in FIG. 8, the first antenna (120) may include at least one first antenna unit (121), and the second antenna (130) may include one or more second antenna units (131).

[0055] Optionally, the second antenna unit (131) and the touch control electrode (110a) within the second region (BE2) may be multiplexed in the structure, and the structures of both may be arranged separately.

[0056] Specifically, the first antenna (120) can be connected to the first antenna terminal (173) through the first wiring (171).

[0057] In some embodiments, at least some touch control electrodes (110a) within the second region (BE2) are multiplexed to the second antenna unit (131).

[0058] The structure of the touch control electrode (110a) multiplexed to the second antenna unit (131) can be connected to the second antenna terminal (174) via the second wiring (172). Since the touch control signal and the antenna signal within the second region (BE2) can be sampled separately using a time division multiplexing method, the multiplexing structure of the touch control electrode (110a) and the second antenna unit (131) does not cause signal interference, and the multiplexing structure of both can further simplify the structure of the display panel (100). Optionally, the display panel (100) further includes a touch control binding terminal, and the touch control electrode (110a) is connected to the touch control binding terminal via the touch control wiring, which is not described in detail.

[0059] In some other embodiments, as illustrated in FIGS. 9 and 10, the second antenna (130) includes a second antenna unit (131), and the second antenna unit (131) and the touch control electrode (110a) are spaced apart, which specifically means that the conductive material constituting the second antenna unit (131) and the touch control electrode (110a) is spaced apart from and insulated from each other.

[0060] For example, the touch control form of the display panel (100) is mutually capacitive, and a plurality of touch control electrodes (110a) are distributed in an array on the same layer, and the touch control electrodes (110a) in the same matrix row or column of the same matrix are electrically connected to each other. One of the second antenna units (131) or a plurality of second antenna units (131) are electrically connected to form an antenna pattern to implement a corresponding antenna function. When the second antenna unit (131) and the touch control electrode (110a) are spaced apart, they do not conduct to each other and furthermore do not cause signal interference between them. By arranging them in this way, the second region (BE2) can combine touch control and antenna functions, while the thickness of the display panel (100) can be further reduced.

[0061] The second antenna unit (131) may be positioned between two adjacent touch control electrodes (110a), and the second antenna unit (131) may be positioned around the touch control electrode (110a), or the touch control electrode (110a) may be positioned around the second antenna unit (131).

[0062] In some optional embodiments, referring to FIGS. 9 and FIGS. 10, at least some touch control electrodes (110a) are positioned around the second antenna unit (131).

[0063] Specifically, the distribution of the second antenna unit (131) may be in a row or column, or the second antenna unit (131) may be distributed in an array, and at least some touch control electrodes (110a) are placed around the second antenna unit (131), that is to say, the second antenna unit (131) is placed inside the corresponding touch control electrode (110a).

[0064] If some touch control electrodes (110a) are placed around the second antenna unit (131), the thickness of the display panel (100) is reduced, and at the same time, the distribution pattern of the touch control electrodes (110a) is not disturbed, thereby ensuring the touch control sensitivity of the second area (BE2).

[0065] The first antenna (120) and the second antenna (130) may each be a long wave antenna, a medium wave antenna, a short wave antenna, an ultra-short wave antenna, or a microwave antenna, and can be selected according to actual demand.

[0066] In some embodiments, the first antenna (120) and the second antenna (130) are both millimeter wave antennas, the first antenna (120) is the main antenna, and the second antenna (130) is used as an auxiliary antenna to amplify the signal of the first antenna.

[0067] Specifically, the functions implemented by the first antenna (120) and the second antenna (130) are identical, and the second antenna (130) can increase the efficiency of signal transmission of the first antenna (120) so that the corresponding antenna function has a better effect.

[0068] In some other embodiments, the first antenna (120) and the second antenna (130) may both be secret limit meter wave antennas, and the first antenna (120) and the second antenna (130) may specifically be configured as one or more of the following: a Bluetooth antenna, a wireless network communication technology (Wi-Fi) antenna, a Global Positioning System (GPS) antenna, a Near Field Communication (NFC) antenna, or a Laser-Direct-structuring (LDS) antenna.

[0069] In some embodiments, the first antenna (120) is an NFC antenna. That is, the short-range wireless communication function of the display device is implemented through the first antenna (120).

[0070] The second antenna (130) may be of the same type as the first antenna (120) or different, and may be placed according to actual demand.

[0071] In some embodiments, the second antenna (130) is an NFC antenna. That is, the near-field wireless communication signal of the display panel (100) is amplified through the second antenna (130) to increase the near-field wireless communication efficiency of the display panel (100).

[0072] In some embodiments, the display panel (100) further includes an antenna layer, and a first antenna (120) and / or a second antenna (130) is disposed in the antenna layer.

[0073] In other words, at least one of the first antenna (120) and the second antenna (130) is placed in the antenna layer and the other is placed in the other film layer, or both the first antenna (120) and the second antenna (130) are placed in the antenna layer.

[0074] The antenna layer may be a single layer or multiple layers. When the antenna layer is a single layer, both the first antenna (120) and the second antenna (130) may be placed in the antenna layer, or only one of them may be placed in the antenna layer. When the antenna layer is multiple layers, the first antenna (120) and the second antenna (130) may be placed in different antenna layers or in the same antenna layer.

[0075] The antenna layer is arranged to facilitate the arrangement of the corresponding first antenna (120) and / or second antenna (130) and to reduce the difficulty of processing the display panel (100).

[0076] In some embodiments, as illustrated in FIG. 4 and FIG. 11, the display panel (100) includes a substrate (140) and a light-emitting layer and a polarizing layer (150) disposed sequentially on one side of the substrate (140), and a first antenna (120) is disposed on the polarizing layer (150).

[0077] In other words, the first antenna (120) is integrated into the polarization layer (150) without the need to place a single film layer separately, thereby further reducing the thickness of the display panel (100). Additionally, by placing the first antenna (120) in the polarization layer (150), signal interference between the first antenna (120) and related elements of other film layers can be reduced, thereby improving the communication efficiency of the display panel (100).

[0078] In an embodiment where the first antenna (120) is placed in the polarization layer (150), the second antenna (130) may be placed in the polarization layer (150) or in other film layers, and may be placed according to actual demand.

[0079] In some embodiments, the second antenna (130) is placed in the polarization layer (150). By placing the first antenna (120) and the second antenna (130) directly on the same film layer, the thickness of the display panel (100) can be further reduced.

[0080] In some embodiments, continuing to refer to FIG. 4 and FIG. 11, the display panel (100) includes a substrate (140) and a light-emitting layer and an encapsulation layer (160) that are sequentially disposed on one side of the substrate (140), and a first antenna (120) is disposed on the encapsulation layer (160).

[0081] In other words, in addition to integrating the first antenna (120) into the polarization layer (150), the first antenna (120) can be integrated into the encapsulation layer (160) without the need to place a single film layer alone, and the thickness of the display panel (100) can still be reduced. Furthermore, in the method of placing the first antenna (120) into the encapsulation layer (160), signal interference between the first antenna (120) and related elements of other film layers can still be reduced, thereby improving the communication efficiency of the display panel (100).

[0082] In some embodiments, the second antenna (130) is placed in the encapsulation layer (160). This allows the film layer thickness of the display panel (100) to still be reduced.

[0083] In an embodiment in which a polarization layer (150) and an encapsulation layer (160) are disposed on a display panel (100), the polarization layer (150) is disposed on one side of the substrate (140), and the encapsulation layer (160) is disposed on one side of the polarization layer (150) away from the substrate (140). At this time, the first antenna (120) and the second antenna (130) may be disposed on the encapsulation layer (160) and may be disposed on the polarization layer (150), or one of them may be disposed on the encapsulation layer (160) and the other on the polarization layer (150), and can be selected according to actual demand.

[0084] The fact that the polarization layer (150) is disposed on one side of the substrate (140) does not mean that the polarization layer (150) is disposed directly on the surface of the substrate (140), and other film layers may be disposed between the polarization layer (150) and the substrate (140). Other film layers may also be disposed between the encapsulation layer (160) and the polarization layer (150).

[0085] In some embodiments, continuing to refer to FIG. 4 and FIG. 11, the display panel (100) comprises an array substrate (170) and a light-emitting layer that are sequentially arranged on one side of the substrate (140), and a first antenna (120) and / or a second antenna (130) are arranged on the array substrate (170). In other words, at least one of the first antenna (120) and the second antenna (130) is integrated within the array substrate (170) of the display panel (100), and thus arranged, the purpose of reducing the thickness of the display panel (100) can still be achieved.

[0086] In some embodiments, the array substrate (170) comprises a metal layer, and the first antenna (120) and / or the second antenna (130) are disposed on the metal layer. That is, at least one of the first antenna (120) and the second antenna (130) is disposed on the metal layer. The array substrate (170) comprises at least two layers of metal, and the first antenna (120) and the second antenna (130) may be disposed on the same metal layer or different metal layers.

[0087] Depending on the different structural forms of the display panel (100), one second display area (BE) may be disposed in the display panel (100) or a plurality of second display areas (BE) may be disposed. In an embodiment in which a plurality of second display areas (BE) are disposed in the display panel (100), the plurality of second display areas (BE) may be adjacent to each other or spaced apart, and, for example, two second display areas (BE) of the display panel (100) are disposed on opposite sides of the first display area (PL), that is, the two second display areas (BE) are disposed parallel to each other.

[0088] In an embodiment in which a plurality of second display areas (BE) are arranged on a display panel (100), the first antenna (120) and the second antenna (130) may be arranged in each of the second display areas (BE), or the first antenna (120) and the second antenna (130) may be arranged in some of the second display areas (BE), and can be selected according to specific needs.

[0089] In some embodiments, the display panel (100) includes at least two second display areas (BE), and the first area (BE1) and the second area (BE2) are placed in at least one of the second display areas (BE).

[0090] Specifically, at least one of the second display areas (BE) includes a first area (BE1) and a second area (BE2), a first antenna (120) is disposed in the first area (BE1), and a second antenna (130) and a touch control electrode (110a) are disposed in the second area (BE2). The other second display area (BE) may have only a display function or may have both a display function and a touch control function simultaneously.

[0091] By placing the first antenna (120) and the second antenna (130) within at least one second display area (BE), the first antenna (120) and the second antenna (130) can be placed within a plurality of second display areas (BE) according to actual demand, providing sufficient space for the placement of the first antenna (120) and the second antenna (130), and further improving the communication efficiency of the display panel (100).

[0092] As illustrated in FIG. 4, in some embodiments, the first display area (PL) is a flat display area, and the second display area (BE) is a folded display area.

[0093] Specifically, the folded display area may be formed by integrally molding together with the flat display area and then folding the edge of the flat display area. The first antenna (120) and the second antenna (130) are placed in the folded display area, and the first antenna (120) and the second antenna (130) are placed using the position of the folded display area. Since there is no need to occupy the position space of the flat display area or the non-display area, it is advantageous for improving the screen occupancy of the display panel (100).

[0094] In some embodiments, the display panel (100) includes at least two folded display areas, and the first area (BE1) and the second area (BE2) are placed in at least one of the folded display areas. In other words, the first area (BE1) and the second area (BE2) may be formed in one folded display area, or of course, may be formed in different folded display areas, thereby allowing the positions of the first antenna (120) and the second antenna (130) to be reasonably arranged according to actual demand.

[0095] A display device according to an embodiment of the present application includes a display panel (100) of any one of the embodiments described above.

[0096] The display device according to the embodiment of the present application includes the display panel (100) of any one of the embodiments described above and thus has the same technical effect, which is not repeated here.
